Why transfa?
Most file-sharing tools are built for humans clicking through UIs. **transfa is built for the terminal** — designed to be called from shell scripts, CI pipelines, and AI agents (Claude, GPT, Cursor, etc.) that need to move files without friction.
- **No signup required** — just install and upload
- **Any format, any size** — up to 100 GB; ML models, archives, binaries, code, media
- **Built for agents** — JSON API, SHA-256 checksums, idempotent uploads
- **Password protection, download limits, TTL** — full control over every link
- **100+ formats detected** — MIME type auto-detection including .gguf, .safetensors, .parquet, .ipynb, and more
